The reason why Zhang Junping only recruited three blacksmiths was also to consider that ordinary people in Muping County also needed blacksmiths to buy kitchen knives, scissors, iron pots and other daily necessities.

"Yes! My subordinates are going to inform them! ”

Sun Xu agreed, took the official document and left, went to inform the blacksmith, and reported to the barracks.

"You want the best craftsmanship!"

"Zhixian, don't worry! I am familiar with the blacksmiths on the scene, and I know who is good at the workmanship! ”

After Sun Xu left, Zhang Junping wrote another letter and asked Zhang Gui to send it to Dengzhou Mansion to Xia Shuai.

Ask him to help recruit Zheng Kui's senior brothers over.

If you can't find it, ask Xia Shuai to help recruit ten more blacksmiths.

Ten blacksmiths were recruited to serve on errands, this little thing, Zhang Junping was not afraid that Xia Shuai would not give face.

After all, he had just given him a lot of credit.

After dealing with these, Zhang Junping had time to think about others.

A large amount of gold and silver was found in the cottage yesterday, and Zhang Junping had already noticed it.

The reason why he didn't squeak was because he didn't want to touch the bottom line of the top ten families in Muping County so early.

It's ridiculous, the top ten families in Muping County still think they are doing secrets, but they don't know that Zhang Junping knows better than them that there are gold mines in Muping and brittle silver mines.

It can be said that Zhang Junping knows more about the mineral resources of Muping County, and even the mineral resources of the entire Dengzhou Prefecture, than the locals of Dengzhou Prefecture.

Dengzhou Prefecture, also known as Yantai in later generations, has gold reserves and is the largest gold producing area in the country and the third largest in the world.

Dengju has not only gold, but also brittle silver deposits.

Brittle silver ore is the ore from which silver is refined.

If Zhang Junping goes up with a piece of paper now, the entire Muping County will be bleeding.

Privately mining gold and silver mines is a great crime of raiding homes and exterminating clans.

However, Zhang Junping does not plan to do that, with the current technology, the gold and silver mines in Dengzhou Mansion are not so easy to mine.

Or the gold and silver reserves that can be mined are not very large.

There are so many gold producing areas abroad, why do you have to work hard at your own doorstep?

Wouldn't it be good to keep them underground?

What Zhang Junping wants to do is to subdue the ten major families and let them use them for their own use.

That's why Zhang Junping pretended not to pay attention to the gold and silver.

Prepare to play slowly with the top ten families in Muping County.

It's ridiculous, today the top ten families are still showing favor to themselves through Liu Daojie, wanting to use reservoirs and canals to involve their energy.

Zhang Junping is also happy that someone takes the initiative to donate money and materials to help him make political achievements.

Originally, he also planned to build a canal to divert water from the middle reaches of the Mishui River to irrigate the land, but now that the ten major families in Muping County are so enthusiastic, Zhang Junping naturally wants to fulfill their enthusiasm.

Pull out a map, that is, a map.

Zhang Junping began to refine his own design plan, the Wuclaw Mountain Canyon reservoir and aqueduct.

The reason why the reservoir was built in the canyon of Wuclaw Mountain is because the terrain here is relatively high, and the storage of water here can better cover the entire coastal saline-alkali land.

The main canal is connected from west to east, passing through the main road from Kunyu Mountain to Muping County, and then turning a corner, along the main road, on the west side of the saline-alkali land, all the way north to the end of the saline-alkali land.

On the east side of the saline-alkali land, there is also a main canal, which is a drainage canal, which is specially used for drainage.

There are also several branch canals connected to the main canal, as well as more bucket canals.

Zhang Junping used branch canals, bucket canals to divide the entire coastal saline-alkali land into several blocks.

This design has the advantage of ensuring that the transformed field will not be flooded and silted.

If there is too much water, it can be discharged directly into the sea through the main drainage canal.

Usually, as long as the side of the branch canal leading to the main drainage channel is blocked, there is no need to worry about the water flowing away in vain.

Moreover, when treating saline-alkali land, it can be treated one piece of land and one piece of land.

Comprehensive governance without eyebrows and mustaches.

Now Zhang Junping has to consider how big each piece is, that is, the spacing of the branch canals.

Zhang Junping's initial plan was to set up a branch canal for one kilometer and a bucket canal for 200 meters.

In this way, each plot is about 330 acres (deducting the area occupied by the bucket canal).

One acre in the Song Dynasty was 60 square feet of Song feet, about 591.576 square meters, about 75 square meters less than now.

When Zhang Junping was writing and painting, Sun Xu came in to report that three blacksmiths and eight blacksmith apprentices had been recruited, and they would report to the barracks three days later.

"Go and get some old craftsmen over!"

"I don't know what kind of craftsmen are needed in Zhixian County!"

"Carpenter, stonemason, old riverman!"

Zhang Junping is good at planning, but if he really designs a reservoir dam, he still needs professional craftsmen.

These craftsmen may not be highly educated, but with a wealth of experience and know-how passed on by word of mouth, they can calculate the structural dimensions of the dam.

To build a 30-meter-high dam, how wide the bottom of the dam needs to be, what kind of materials need to be used, and how much labor is needed, experienced craftsmen can calculate it.

"Got it, my subordinates are going to ask for someone!" Sun Xu naturally knew about Zhang Junping's construction of reservoirs and canals, and also knew that the top ten families were ready to spend money to buy peace and support Zhang Junping in building reservoirs and canals.

After a short time, Sun Xu came to the county government with seven or eight craftsmen.

"This official invited all the masters to come over, I hope that you can help the officials to consult, the construction of the reservoir dam, and the construction of the canal!" Zhang Junping was still very polite to these old craftsmen, and politely invited everyone to sit down before he opened his mouth to say his request.

"Report to the county magistrate, this needs to see what kind of materials are used!

If an earthen dam is built, then the height of 30 meters, the width of the bottom of the dam needs to be 150 meters to ensure that the dam will not be washed away by water.

In order to ensure that the dam is not eroded by water, the land dam also needs to be built with stone masonry to protect the slope! After listening to Zhang Junping's words, Lao Hegong thought about it in his heart for a while before he spoke.

"So how much manpower does it take to build such a dam, and how long will it take to build it?"

"Back to Zhixian County, this needs to be checked on the spot to see how long the embankment needs to be built to calculate!" The carpenter spoke.

"Okay, Sun Dutou, you go and arrange two carriages, and the official will accompany a few masters to the Wuclaw Mountain Canyon to check the construction of the embankment!"

Zhang Junping is also a resolute character, he left as soon as he said he would, and directly ordered Sun Xu to arrange the carriage.

"Whoa!" Sun Xu agreed, turned around and went out to arrange the carriage.

Zhang Junping rode a horse, and several masters rode a carriage to the Wuclaw Mountain Canyon.

"Ladies and gentlemen, this official is preparing to build a reservoir here to adjust the water level of the Shui River!" Zhang Junping pointed to the Wuclaw Mountain Canyon and introduced.

"Once the reservoir is built here, you can split the river in two at its source, so you don't have to worry about the disaster of the river swelling and breaking the dam in the summer!

In the dry season, you can release the water from the reservoir to water the crops! ”
